, 'My invention relates to shower bath fixtures andmore particularly to"shower bathheads of the type disclosed in my co-pending application,

Serial No. 229,596, filed September 12, 1938. In

my said prior application a hollow perforated spherical cap or sprinklermember is mounted .inthe-body portion of the sprinkler head forswiveling movement therein to thereby permit convenient direct'ion ofwater flowing through the perforations at any desired angle to the axisv of the head. -'Some difficulty has been experienced with my priorconstruction'due to the clog ging oi the sprinkler perforations. v Theobject-of the present invention is to so construct the swiveling memberthat it will be practically self cleaning or can be quickly andconveniently cleaned without. disassembling any of the'parts thereof.

Another object of the invention is to provide a self cleaninguniversally movable shower bath spray head which is of economicalconstruction and easy to assemble. 1

Other objects and advantages of theinvention will be apparent when thespecification is consid- I ered withthe accompanying drawingi'in which:

Referring more particularly to the drawing I denotesin general a showerhead constructed in accordance with my invention and comprising a Lhollow bell shaped body member 2 having a reduced internally threadedupper end 3 adapted to be connected to awater supply pipe, not

shown. The open mouth 4 of the body 2 is suf ficiently large to receiveand house a semi-spher ical sprayer or head member 5 through which wateris sprayed in a manner ,presently underview of the gasket or pack-Figure 5 is a plan-view of the small split lockstood. An annular grooveor recessBfl is formed in the inner walloi body 2, adjacent the lower"edge thereof in which is seated a suitable gasket or" packing gland orthe like 3|. The inner face of the gasket engages with the curvedsidewall of the sprayer head member 5 and forms a-fiuid tight seal betweenthe head and body 2, thereby.

permitting free angular or swivel movement of the head without anydanger of leakage between thesepartsfl The lower or outer end 6 of thespray head a or member 5, pr'ojectsfoutwardly a slight dis! tancethrough the mouth 4 of body .2, and is provided with a water outletopening I. The wall 8 of this opening is beveled downwardly. and

outwardly at an angle about four degrees (4) to the axis of body member2, for the reception of'a spraying disk 9, formed with'a correspondinglyshaped periphery [0. The peripheral surface in is formed with an equalnumber of equally spaced alternately arranged V-shaped grooves H and I2of uniform depth throughout their entire length, the grooves ll beinginclined out wardly and downwardly at an angle of approximately twodegrees (2) from the longitudinal axis of the body member 2, and thegrooves ll beinginclined outwardly and downwardly at an angle ofapproximately six degrees (6) from the longitudinal axis of the bodymember 2. The

difference in relative angularity betweenthe two sets of grooves isindicated in drawing. 7 I v The spraying disk 9 is slidably mounted on astem l3v which extends through a central opening l4 in ,thedisk and isadjustably connected Figure 9 of the "at its inner or upper threaded endto the cross-head or spider. I6 carried by. the disk, the

spider being formed with athreaded opening H for this purpose. A smallsplit ring I8 and a shoulder I9 respectively confine the disk!) slidablyon the stem, and a larger split safety ring 20, seated in an annulargroove 2| formed in the inner wall of the body 2 below the groove 30,serves to prevent the head 5 from dropping out p of the body 2, shouldthe gasket 3| become worn or otherwise damaged. The outer endof stem I3is formed with a handle portion 22 for 'convenient manipulation of thehead 5 and its disk member 9, relativelyto the body 2, when the userdesires to change the angular direction of the waterflow through thedischarge opening 1. r

The range of this adjustment is limited by means inner face of the body2. and adapted to be engaged by the upper peripheral edge 24 of sprayer.

of an internal annular flange 23 formed on the i head 5 when the latteris moved in the manner indicated by the dotted lines of Figure 1. Therange of movement is such that the grooves H and [2 will never beobstructed or closed by the inner face or wall of the body member 2.

By virtue of the difierence in inclination of the two sets of grooves I!and I2 the water will be discharged in the form of inner andouter spacedcones 25 and 25 respectively, the'ginner coneflow ing from the groovesH'and the outer cone from the grooves 12, as illustrated in Figure 9,wherein the line 26 represents the slope of the peripheral face H] ofthe disk 9 and the lines 2! and 28 indi cate the slope or inclination ofthe grooves I I and i2 respectively, relatively to'the longitudinal orvertical axis of the various parts of the shower .hea'd.

When the stem I3 is screwedhome in the spider l6 sufficiently far tocause the peripheralface H] 'of disk 9 to completely register with thewallof" discharge opening I, a shoulder 29 on the stem engages thespider and acts as an additional stop,

shoulder l9. If the stem is now unscrewed av distance represented by thespace between the split ring I8 and the hub portion 32 of the disk '9,the periphery l!) of the latter will'clear the Wall 8 of opening I andgrooves l I and 12 can be thoroughly flushed. If this flushingdoes'nothave the desired cleaningefifect, the disk can be manuallyreciprocated on the stem withinthe limits of the space previouslymentioned or the grooves can be wiped off witha cloth or the like shouldthis be necessary.

Having thus described rny invention, what I s claim is:
